It serves as a template or framework where designers can place their flyer designs to preview how they would appear when printed or digitally published. These mockups often mimic various real-world scenarios, such as a flyer being held by a person, placed on a desk, or hanging on a wall, providing a sense of scale, context, and visual representation. They are useful tools for designers to showcase and present their designs to clients, allowing for a more accurate visualization of the final product before it's actually produced or distributed. This aids in assessing the design's effectiveness, layout, and overall visual appeal, ensuring the flyer meets the desired objectives before finalization and distribution.
